[0003] However, it still has some disadvantages. For example, when traditional transformers dissipate heat, multiple fans or oil pumps are usually used for cooling and heat dissipation. Although the fans and oil pumps can ensure stable heat dissipation of the transformer, after long-term use, the fans and oil pumps will consume a large amount of energy, resulting in energy waste. Its heat dissipation efficiency and energy consumption cannot be proportional, and the energy consumption is greater than the heat dissipation efficiency.

[0004] To solve the above problems, an energy-saving transformer is proposed in this application. Content of the Utility Model

[0009] Preferably, an oil return pipe is fixedly connected to the outer surface of the lower end of the oil tank. The lower outer surfaces of the input pipe and the oil pump are connected to a first heat conduction plate in a communicating manner. One side outer surface of the first heat conduction plate is connected to a second heat conduction plate in a communicating manner. The numbers of the first heat conduction plate and the second heat conduction plate are both two groups. A connecting pipe is fixedly connected between the first heat conduction plate and the second heat conduction plate.

The fan blade is located on the other side outer surface of the fixed frame. A filter screen is fixedly connected to the inner wall of the front end of the motor housing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By means of the heat dissipation assembly provided in the present utility model, first start the oil pump. Under the action of the oil pump, the cooling oil is input into the first heat conduction plate and the second heat conduction plate.
